All you need is basic metric tools...
I replaced the missing radiator on the 2004 Hyundai Sonata (same car) that I was rebuilding for my daughter.... Two hoses, one top - one bottom, and two transmission cooler lines on the bottom...remove the top retainers that have the rubber grommets, disconnect the fans and pull the radiator out, remove the fans from the old radiator and install on the new... Reverse the above and you are done...
